Good going Craig. It's important to make people think.

Regarding kids, I think kids are overall much more out-of-shape these days from sedentary lifestyles. When my kids were in elementary school (15 years ago), they were some of just a few students, who could scamper up a rope climb. My had no TV and they were kicked out of the house to play in the woods and on the rope swings, all the time. Pre-computer games too.
